There's a library composer who's been placed 40,000 times. Do the math and it works out to one cue a day, every day, for 15 years.
What I see is consistent output aimed at about 80% instead of chasing perfect.
Most people can't even tell the difference between someone's 80% and their 95%. If you're stuck polishing one track for a week, you're optimizing for the wrong thing.
What's your "aim for 80%" number: how many tracks could you actually finish this month if you stopped chasing perfect?
